🛡️ Is 305 Area Code Spam or Scam?
Like most US area codes, 305 is used by both legitimate callers and scammers. The code itself is perfectly real — millions of people and businesses in Miami use it daily. But scammers frequently spoof 305 numbers because local-looking calls get answered more often than unfamiliar ones.
